What does deadbolt installation actually involve?
A deadbolt is the lock on your door that actually stops somebody. The spring latch in a doorknob only keeps the door shut against a breeze. It was never meant to resist a shoulder, a pry bar, or a credit card. A deadbolt throws a solid steel bolt, usually about an inch long, into the door frame, and it only moves when a key or a thumb turn moves it. People call us for deadbolt installation in Maywood for a handful of plain reasons:
None of these jobs is complicated, but each has a right way and a sloppy way. A deadbolt drilled a few degrees off, or set into a weak frame, looks fine on the day and fails the first time someone leans on the door. If your door was damaged in an attempted break-in, or you can't secure it tonight, call us at any hour. We'll treat it as an emergency locksmith job and close the door up properly.
- The door has only a knob latch and no deadbolt at all
- The existing deadbolt is worn: the key grinds, the cylinder spins, or the bolt sticks
- The door or frame was kicked or pried and the lock no longer holds
- You moved in and have no idea who still has a key
- The bolt no longer lines up with the strike plate
- A glass panel or sidelight near the door makes a keyed inside cylinder worth considering
Single-cylinder or double-cylinder: which deadbolt fits your door?
A single-cylinder deadbolt takes a key outside and has a thumb turn inside. It is the right lock for most entry doors, because anyone inside can leave in one motion without hunting for a key in the dark or in smoke.
A double cylinder deadbolt takes a key on both sides. We do double cylinder deadbolt installation when there is a real reason for it. The usual one is a door with a glass panel or a sidelight within arm's reach of the thumb turn, where someone could break the glass, reach in, and turn the lock. A keyed inside cylinder defeats that trick.
The tradeoff is serious, and we explain it every time. If the key is not in the lock or close at hand, you can be trapped inside during a fire or other emergency. Many building and fire codes restrict keyed-both-sides locks on residential exit doors, and some leases do too, so confirm with your landlord or the local building department before you commit. If a thumb turn will do the job, we'll tell you it is the better choice. Where a double cylinder is allowed and makes sense, the usual practice is to keep the key in a fixed spot near the door, out of reach of the glass, and make sure everyone in the household knows where it is.
Beyond the cylinder count, deadbolts come in grades under the ANSI/BHMA standard. Grade 1 is the heaviest duty and grade 3 the lightest of the residential grades. We can supply hardware across that range and match it to your door and how you use it.

Call (213) 577-1366How do we install or replace a deadbolt, step by step?
Whether it's a brand-new deadbolt installation or a deadbolt replacement in an existing hole, the sequence is the same. We cover wider hardware work under lock installation. This is the deadbolt-specific version.
The alignment step is what separates a deadbolt that works for years from one that sticks by August. We don't leave until the bolt extends fully, moves freely, and doesn't lift or pull the door when the door is closed.
- Inspect the door and frame. We check the door material, thickness, and edge condition, any existing holes, and whether the frame is solid or split.
- Choose the hardware. We settle single or double cylinder, the grade, the backset the door needs, the finish, and whether you want the lock keyed to match others you own.
- Mark and drill. For a new installation we use a template and a hole saw for the large cross bore and a smaller bore through the door edge. On a replacement, the holes are usually already there, and we fix them with trim plates if they've been worn oversized.
- Fit the bolt. We set the latch into the door edge, mount it flush, and install the cylinders and thumb turn or inside key cylinder.
- Set the strike. We cut the jamb cleanly and install the strike plate with long screws that bite into the framing behind the jamb, not just the trim, because that is where kick-ins are won or lost.
- Align and test. We cycle the bolt with the door open, then closed, many times, and adjust until nothing drags. If the door itself is swollen or sagging, we tell you what it needs.
- Hand over. We test every key, show you how the lock works, and tell you what to do if it ever feels stiff.
What affects the cost of deadbolt installation in Maywood?
We don't put numbers on a web page, because the honest answer depends on your door. What we can do is tell you what moves the price, so nothing surprises you.
The lighter-cost option is usually a straight deadbolt replacement on a sound door whose holes already match, because there is no drilling or frame work. A first-time installation on a door that has never had a deadbolt takes more labor. We explain the cost for your particular door before we start work, and if there is a more economical route that still does the job, we say so.
- New installation versus replacement in an existing hole
- Door material and condition, including thin or worn edges and oversized old holes
- Frame repair or reinforcement if the jamb is split or soft
- Hardware grade and finish
- Single-cylinder versus double-cylinder, and any special keying
- How many doors you want done in one visit
- Time of day, since after-hours calls take us out of our normal schedule
- Travel to your address from our Westwood base

Call (213) 577-1366Should you replace the deadbolt, rekey it, or add a new one?
Not every deadbolt problem needs a new deadbolt. If the lock works smoothly and you only worry about who holds keys, rekeying the lock changes the key without changing the hardware, and that is often the more economical route.
Replacement makes sense when the hardware itself is the problem: a key that grinds, a cylinder that spins, a bolt that sticks even when the door is aligned, a lock forced during a break-in, or a light-duty deadbolt on a door that deserves a heavier one. If several locks on the property are mismatched or worn, the job may grow into wider lock replacement work, and we'll tell you which one you are looking at.
Adding a new deadbolt is the right call when the door has only a knob latch. A security screen door in front doesn't change that, because the screen's lock protects the screen and not the main door behind it.
Deadbolt installation in Maywood: bungalows, apartments, and rear units
Maywood covers about 1.2 square miles and is among the most densely populated cities in California. The housing is mostly small 1920s-1940s bungalows, many with a rear unit, plus two- and three-story apartment buildings, and most households rent. That shapes deadbolt work across ZIP 90270 in specific ways.
Summer is the seasonal issue. Inland Maywood has hot, dry summers, and the marine layer rarely holds past morning. Heat can swell wooden doors in older buildings, and a swollen door shifts just enough to make a bolt drag in its strike. We check the fit with the door as it sits that day, leave a little clearance, and tell you if the door needs planing before any lock will behave.
Security screen doors are widespread on older homes and apartment entries here. Before we pick hardware, we check that the screen door swings far enough that it won't block your hand or key at the deadbolt, so you aren't fighting two doors every time you come home.
Our storefront is at 10740 Wilshire Blvd in Westwood, about 18 miles from Maywood, and our mobile vans bring the hardware, templates, and tools to your door.
- Bungalows and rear units: older wood doors can be thin or have worn, oversized holes from earlier locks. A rear unit deserves its own deadbolt and its own keys, separate from the front house.
- Atlantic Boulevard and Slauson Avenue corridors: apartment entries near these streets are matched to the existing door prep. Between tenants, a deadbolt swap or a rekey is the usual step, and if you're locked out before that happens, see apartment lockout.
- Riverfront blocks near Maywood Riverfront Park, northern Maywood near Vernon, and southern Maywood near Bell: the work is the same wherever the door is, and the door itself tells us what it needs.

Call (213) 577-1366Renting in Maywood: who decides on a new deadbolt?
Most households in Maywood rent, so this question comes up a lot. Read your lease and talk to your landlord first. Some leases require landlord approval for lock changes or require the landlord to hold a key, and a double-cylinder deadbolt on an apartment entry can raise code and safety questions. We'd rather you sort that out before we drill than after.
Landlords and property managers with several units can have us install matching deadbolts, set up the keying so each unit has its own key, and handle turnover between tenants. More on that at locksmith for landlords.
Is a basic deadbolt enough, or do you need more?
For many doors, a well-installed deadbolt of the right grade is enough, and the installation matters more than the label on the box. A strong deadbolt in a weak frame still loses to a kick. That's why we put so much attention into the strike and the screws behind it.
If you want more resistance to picking, drilling, and bumping, ask about high-security locks, which use restricted keyways and tougher construction. If you'd rather not carry keys, smart lock installation puts a keypad or app-driven deadbolt on the same door. A smart lock depends even more on a smooth, aligned bolt than a mechanical one does, and it runs on batteries you have to look after.

Frequently asked questions
Can you install a deadbolt on a door that never had one?
Usually, yes. The door has to be thick and solid enough to take the bore holes without weakening the edge. We inspect it first. If it's a thin or damaged door that can't hold a deadbolt properly, we'll say so rather than install a lock that won't last.
Is a double cylinder deadbolt allowed on my Maywood apartment door?
We can't give a legal ruling. Many building and fire codes restrict keyed-both-sides locks on residential exit doors, and leases can too. Check with your landlord or the local building department. If a thumb turn is workable, we'll recommend it as the safer choice.
How long does deadbolt installation take?
A straightforward replacement on a sound door is a short job. A new installation that needs drilling, or a frame that needs reinforcing, takes longer. We can give you a realistic sense of the work once we've seen the door.
Will my old keys work with the new deadbolt?
A new deadbolt comes with its own keys, so your old key won't fit it. In many cases we can key it to match other locks you own, depending on brand and keyway. We confirm that on site before we order or install anything.
My door sticks every summer. Will a new deadbolt fix it?
Not by itself. Heat can swell wooden doors in older buildings, and a swollen door pulls the bolt out of line. We check the fit and leave clearance for the strike. If the door needs planing or adjusting, we tell you.
Can you replace a deadbolt that was forced during a break-in?
Yes. We replace the lock and check the door edge and frame, since forced entry often splits the jamb. If it's night or you can't secure the door, call (213) 577-1366. The line is answered around the clock.
Do you do deadbolt installation at night or on weekends?
Yes. Our phone is answered 24 hours a day, 7 days a week, year-round. Non-urgent installs are easier to schedule during the day, but if your door won't lock after hours, call and we'll work out what to do.
What should I ask any locksmith before hiring them?
Ask for their California BSIS LCO license number, since the state requires locksmith companies to hold one. Ask them to explain the cost for your specific door before work starts, and to say what's included. A locksmith who dodges those questions is one to skip.
